This entry is being used for tracking a regression from 2.6.36. Please don't
close it until the problem is fixed in the mainline.
According to the referenced thread the resolution is to drop the autofs4_ioctl_mutex, as it is probably not needed.
I thought Arnd Bergmann would post an update to his patch
series to remove that mutex.
If Arnd is too busy I can do the patch, Arnd?
Ah, sorry about that, I thought you'd post the patch ;-)
I'd be happier if you can do the patch yourself, since you can actually test it.
